JAR-CLOSURE.

. Specification of Letters Patent.

Patented June 1, 1920.

Application filed February 14, 1919. Serial No. 277,065.

- out necessitating the use of a rubber gasket.

Another object of the invention is to provide a cover between which and the jar is indicator to show whether or not the con-,

tents remain intact.

\Vith the foregoing and other objects 'in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a vertical section through the upper portion of a jar equipped with this improved closure,

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1, and

Fig. 3 's a detail sectional view showing a slightl different form of the invention.

In the embodiment illustrated in Figs. 1 and 2 a glass fruit jarl is shown having the usual upstanding neck 2. This neck 2 is provided at the mouth around the perimeter with segmental. cutout portions 3 to receive cam-shaped segmental sections 6 carried by the closure 5 as,will -.be hereinafter more fully described. This neck 2 also has annular segmental grooves 4 which are arranged in substantial horizontal alinement with the bottom portions of the recesses 3 to receive the locking segments 6 when a partial turn is imparted to the cap-like closure 5.

on its upper face as'shown at 8 for a pur-' pose to be described' The jar 1 has the usual shoulder 9 between the neckv 2 and the body portion and ex-.

tending upwardly from the outer edge of said shoulder is an annular flan e 11 be-- tween which and the bevel-edge o flange 7 is formed a groove 12 to receive a sealing material shown at 13 which is preferably sealing wax or paraffin. This groove is substantially V-shape in cross section so that when the sealing material is inserted an air-tight connection will be formed be-.

tween the jar and its closure. This sealing material will indicate if there is any leakage since bubbles will appear at the surface thereof.

From the above description it will be obvious that the closure 5 may be readily applied to the jar by positioning it over the mouth of neck 2, with the segments 6 arranged to register withlthe recesses 3, and when said cap is lowered with these segments extending into the recesses, and a partial turn imparted thereto, the segments will pass into the grooves 4 in the jar neck and securely lock the closure to the jar. After the parts have been so assembled the sealing material is applied in the manner above set forth.

In the form shown in Fig. 3,-the jar 1 is constructed the same as jar 1 shown in the other figures with the upstanding annular flange 10, the neck 2 thereof instead of having the recesses and undercut grooves, is provided with the usual screw threads 5 The jar closure 5 is also threaded in the usual manner, the flange 7 thereof being beveled to form the V-shaped groove between it and flange 10 to receive the sealing material.

From the foregoing description, taken in connection with the accompanying drawinvention together with the device which I I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent, is The combination of a jar having an upstanding neck with segmental cutout portions in its mouth around the perimeter thereof, said neck also? having peripherally disposed grooves on its inner face connecting said cutout portions below the outer edge of the neck and a cap like closure for said ar with an annular outstanding flange on the edge. thereof, the periphery of which .isbeveled on its upper face said closure also having locking segmental ribs on the inner face of the side walls thereof adapted to register with the cutout portions of the 15 beveled edge of the closure to receive a seal- 20 ing material.

11 testimon whereof I afiix my signature in presence 0 two witnesses.
